Following the huge success of ITV’s powerful true-story drama, Mr Bates vs the Post Office, about the shocking Post Office scandal, there’s been an increase in similar high-impact dramas based on real stories.

What is Dirty Business about?

The series centres around Ash (Thewlis), a former police detective who notices that his local river is becoming increasingly polluted. He teams up with his neighbour, Peter (Watkins), a Professor of Computational Biology, to establish that their local sewage works is not treating sewage correctly, subsequently and frequently dumping raw, untreated sewage into local waterways.

Meanwhile, Asim Chaudhry (People Just Do Nothing) stars as whistleblowing sewage plant worker Mickey, who partners with Ash and Peter to supply information on critical failures from the inside.

The series is based on a decade-long investigation about water companies dumping raw sewage

The synopsis continues: “Dirty Business also follows the true story of the Preen family, wracked by grief when their 8-year-old daughter Heather dies after contracting e-coli 0157. Heather had been playing on a beach where days earlier a nearby storm pipe had discharged into the sea.

“The Preens believe Heather’s death was the result of her coming into contact with the raw sewage. It also follows the story of young surfer Reuben who believes his chronic illness, Meniere’s disease, is as a result of surfing in polluted water, changing his life forever.”

Also starring in the drama are Posy Sterling (Lollipop) as Julie Preen, Charlotte Ritchie (Grantchester) as Sophie Harrison, Craig Parkinson (Grace) as John Bull, Alex Jennings (The Crown) as Sir James Bevan

Rounding out the cast are Tom McKay as Mark Preen, Alice Lowe as Susan Davy, Chanel Cresswell as Hanna Smith, Vicki Pepperdine as Lucy Hunt, Juliet Cowan as Debbie Henderson, Tom Durant-Pritchard as Chris Hines and Stephen Wight as Alex Sinclair.
